Eye Problem	Description
Popeye (Exophthalmia)	One or both eyes bulge outwards, often caused by poor water quality, injury, or infection.
Cloudy Eye	Eye becomes cloudy or opaque, possibly due to bacterial infection, parasites, or injury.
Eye Flukes	Small parasites attaching to the eye, causing irritation and inflammation.

Common Betta Eye Problems: What to Look For

Popeye (Exophthalmia): One of the most noticeable eye issues in bettas is Popeye, a condition where one or both eyes protrude or bulge outward. This bulging can be caused by bacterial infections, injuries, poor water quality, or even a gas bubble disease. Along with the bulging, you might observe cloudiness, redness, lethargy, and a decreased appetite in your betta.

Cloudy Eye: A cloudy or hazy appearance over the eye is another common problem. This is often a result of bacterial or fungal infections, parasites, injuries, or subpar water conditions. Your betta might also experience redness or swelling around the eye.
Other Eye Issues: Bettas can also develop cataracts, which appear as cloudiness within the lens of the eye, or corneal ulcers, which are open sores on the cornea.

A healthy betta’s eyes are a window into their overall health. They should be round and symmetrical, proportional to the size of their head. The eyes should be clear and bright, free from any cloudiness or film. When your betta swims, their eye movements should be smooth and coordinated. If you notice any deviations from these characteristics, it could be an indication of an underlying problem. Learn more about popeye / bulging eyes here.

Treating and Preventing Betta Eye Problems

Seeking Professional Help: If you notice any abnormalities in your betta’s eyes, it’s crucial to consult a veterinarian who specializes in fish. They can diagnose the issue and recommend treatment.

Home Care and Remedies: Depending on the cause, you can try some home remedies while awaiting veterinary advice. For mild cases of Popeye, Epsom salt baths can sometimes help reduce swelling. If the problem is related to water quality, immediate partial water changes and addressing the root cause are essential. It’s also important to quarantine any affected fish to prevent the spread of infection.

Cloudy Eye

A hazy or opaque appearance in one or both of your betta’s eyes is indicative of a cloudy eye. This condition often stems from bacterial or fungal infections, parasites, injuries, or poor water quality. Accompanying symptoms may include redness or swelling around the eye, lethargy, and a decreased appetite.

Treatment and Prevention:

Water Quality: If water quality is the culprit, immediate partial water changes and addressing the underlying issue (such as ammonia spikes or high nitrite levels) are crucial.
Medication: For bacterial or fungal infections, consult a veterinarian for appropriate medication. Antifungal or antibacterial treatments might be necessary.
Quarantine: Isolate the affected betta to prevent the spread of infection to other fish in the tank.
Supportive Care: Maintain pristine water conditions, ensure adequate filtration and aeration, and feed a nutritious diet to bolster your betta’s immune system.

Eye Flukes

Eye flukes are tiny parasites that latch onto a betta’s eyes, causing irritation, inflammation, and discomfort. You might observe your betta rubbing their eyes against objects or flashing (darting around erratically) in an attempt to dislodge the parasites.

Treatment and Prevention:

Medication: A veterinarian can prescribe anti-parasitic medication to eliminate eye flukes.
Quarantine: Isolate the affected betta to prevent the spread of parasites to other fish.
Water Changes: Perform frequent partial water changes to help reduce the number of parasites in the tank.
Cleanliness: Maintain a clean tank environment to minimize the risk of parasite infestations.

Cotton Wool Disease

Cotton wool disease, a fungal infection, can manifest as white, cottony growths on your betta’s eyes, causing them to appear swollen and irritated. This condition often arises due to stress, poor water quality, or a weakened immune system.

Treatment and Prevention:

Medication: Antifungal medication prescribed by a veterinarian is typically necessary to treat cotton wool disease.
Water Quality: Improve water quality by performing frequent water changes and ensuring proper filtration.
Stress Reduction: Minimize stress by providing a suitable environment with ample hiding places and avoiding overcrowding.
Quarantine: Isolate the affected betta to prevent the spread of the fungal infection.
